RedHill Biopharma Reports Positive Results for Opaganib in Combination with Venetoclax for CLL Treatment
RedHill Biopharma Ltd. (NASDAQ: RDHL) has announced promising in vivo results showing that the combination of opaganib with venetoclax significantly reduces Chronic Lymphocytic Leukemia (CLL) cells. The study indicates that adding opaganib, a potent sphingosine kinase 2 (SPHK2) inhibitor, to the existing venetoclax regimen may provide an effective strategy to combat venetoclax resistance in CLL patients.
Understanding Venetoclax Resistance in CLL
Resistance to venetoclax, a leading therapy for CLL with estimated sales of $2.5 billion, poses a significant therapeutic challenge. Research reveals that SPHK2 is frequently overexpressed in venetoclax-resistant cancer cells, allowing these cells to persist even in combination therapies. Inhibition of SPHK2 has been shown to potentially reduce T-cell activation and proliferation in these resistant CLL cells.
Key Findings from the In Vivo Study
The latest in vivo study demonstrates that the addition of opaganib to venetoclax leads to a remarkable 50% reduction in CLL cell counts (CD19⁺, CD5⁺) compared to control groups. Moreover, this combination also resulted in decreased levels of CD3⁺, CD4⁺, and CD8⁺ T cells, while lowering PD1 expression in CD8+ T cells. These findings suggest a strong potential for opaganib as an adjunct therapy in managing venetoclax-resistant CLL.
- 50% reduction in CLL cell counts when combined with venetoclax
- Decreased CD3+, CD4+, CD8+ T cell counts
- Ongoing Phase 2 study for opaganib + darolutamide in prostate cancer
Implications for Future CLL Treatments
Dr. Romina Gamberale, who led the study, emphasized the importance of understanding resistance mechanisms in targeted therapies such as venetoclax. "This study indicates that opaganib may play a significant role in reducing BCL-2 inhibitor resistance, potentially enhancing treatment options for CLL patients," she stated.
Dr. Mark Levitt, Chief Scientific Officer at RedHill, pointed out that maintaining the effectiveness of venetoclax is crucial for improving treatment outcomes. He remarked, "The data supports the premise that opaganib has great potential in reinforcing venetoclax-induced therapies and now includes CLL as a significant indication."
